范围:本欧洲标准规定了所有类型滚压的排放和抗扰度要求 股票它包括牵引车、牵引车和火车组，包括城市街道上使用的城市车辆。本欧洲标准规定了机车车辆对外界的排放限值。 本部分标准的范围在车辆与其各自能量输入和输出的接口处结束。对于机车、列车组、有轨电车等，这是集电器（受电弓、蹄形齿轮）。对于拖运物料，这是交流或直流辅助电源连接器。然而，由于集电器是牵引架的一部分，因此不可能完全排除该接口与电源线的影响。慢速移动测试旨在将这些影响降至最低。 EMC计划（如EN 50238中规定）中确定的铁路系统内可能存在额外的兼容性要求。 基本上，要集成到车辆中的所有设备都符合EN 50121-3-2的要求。如果EMC 5012与另一个标准设备的完全集成符合EN 5012，但EMC 5012与另一个标准设备的完全集成不符合EN 5012。 EN 50121-2中涉及整个铁路系统的电磁干扰。 这些具体规定将与EN 50121-1中的一般规定一起使用。 考虑的频率范围为0 Hz（DC）至400 GHz。无需在未规定要求的频率下进行测量。 交叉引用:CISPR 16-1-1:2010EN 55016-1-1:2010+A2:2014EN 50121-1:2017EN 50121-2:2017EN 50121-3-2:2016EN 50122-1:2011ITU-T O.41:1993EN 50238ITU-T K.68:2008包含以下内容:修订，2019年5月

Scope: This European Standard specifies the emission and immunity requirements for all types of rolling stock. It covers traction stock, hauled stock and trainsets including urban vehicles for use in city streets. This European standard specifies the emission limits of the rolling stock to the outside world. The scope of this part of the standard ends at the interface of the rolling stock with its respective energy inputs and outputs. In the case of locomotives, trainsets, trams etc., this is the current collector (pantograph, shoe gear). In the case of hauled stock, this is the AC or DC auxiliary power connector. However, since the current collector is part of the traction stock, it is not entirely possible to exclude the effects of this interface with the power supply line. The slow moving test has been designed to minimize these effects. There may be additional compatibility requirements within the railway system identified in the EMC plan (e.g. as specified in EN 50238). Basically, all apparatus to be integrated into a vehicle meet the requirements of EN 50121-3-2. In exceptional cases, where apparatus meets another EMC Standard, but full compliance with EN 50121-3-2 is not demonstrated, EMC is ensured by adequate integration measures of the apparatus into the vehicle system and/or by an appropriate EMC analysis and test which justifies deviating from EN 50121-3-2. Electromagnetic interference concerning the railway system as a whole is dealt with in EN 50121-2. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1. The frequency range considered is from 0 Hz (DC) to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.Cross References:CISPR 16-1-1:2010EN 55016-1-1:2010+A2:2014EN 50121-1:2017EN 50121-2:2017EN 50121-3-2:2016EN 50122-1:2011ITU-T O.41:1993EN 50238ITU-T K.68:2008Incorporates the following:Amendment, May 2019
